T all whom it may concern:

Be it known that I, DANIEL KELLEHER, a citizen of the United States ofAmerica, residing at Sandusky, in the county of Erie and State of' Ohio,have invented certain new and useful Improvements in Machines forScoring Blanks of Cellular Board, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention relates to the manufacture of scored blanks of cellularboard designed for use in the manufacture of paper boxes and similararticles, and the invention comprises the novel means employed forscoring the stock which avoids overstressing or tearing the same andproduces a score permitting the bending of the blank in oppositedirections.

In the drawings: Figure 1 is a side elevation of the machine; Fig. 2 isa cross section thereof; and Figs. 3 and 4 are cross sections of thescored blank respectively bent in opposite directions.

My improved machlne comprises essentially a pair of traveling belts orendless members which are of a cross section to form on the one a tonguemember'and on the other a complementary groove member. Thesev belts arearranged with their adjacent strands in slightly angular relation, sothat at one end the tongue is in engagement with the groove while at theopposite end these members are separated topermit of the insertion ofthe stock.

In detail, A is, one of the endless belts traveling upon pulleys B andof a cross sec: tion having a projecting tongue portion C D is thecomplementary belt traveling over pulleys Band of a cross sectionforming the groove F. ,Upon opposite sides of this groove are portions Gwhich are beveled on their outer edges and which are arranged oppositestraight laterally-project ing portions H on the belt A on oppositesides of the tongue G. i

I are guides for the belts A and B to maintain the adjacent portionsthereof straight.

The pulleys B and E are so arranged that the adjacent portions of thebelts A and B are at one end 1n engagement with each other while at theopposite end they are slightly separated. This permits of feeding thecellular board in between the sepa- Specification of Letters Patent.

rated endsof the belt and during the movement ofthe stock with the beltsthe tongue C will be gradually forced downward into the groove F. Thiswill first press down the cellular structure and then draw the materialinward from each side. As the material is thus drawn in it is'forced'over the beveled faces G which also will ress down the cellularstructure and will orm a reverse groove in the stock. Thus when thestock is removed it is formed with a central score deflected to one sideand adjacent parallel scores deflected toward the other side asindicated atJ and K. This will permit of bending the blank in eitherdirection without tearing or unduly stressing the stock.

. What I claim as my invention is:

1. A blank scoring mechanism comprising a pair of endless travelingmembers respectively having a tongue and a groove cross section, theadjacent portions of said members being in slight angular relation, withthe tongue and groove in engagement at one end and slightly separated atthe opposite end.

2. A blank scoring mechanism comprising a pair of endless belts havingportions adjacent to each other and respectively of a tongueand groovecross section, pulleys over'which said belts travel relatively arrangedto engage the tongue and groove at one end and separate them at theopposite end, and guides over which the adjacent portions of said" beltstravel to hold the same from lateral displacement.

3. A blank scoring mechanism comprising an endless belt and anadjacentvmember having complementary tongue and groove cross sections,said members being relatively arranged to engage the tongue and grooveat one end and to separate the same at the opposite end, the directlycooperating portions of the two members being substantially rectilinear.

4. A blank scoring device comprising a flexible traveling member havingits cross section fashioned to form a score, a' guide for holding aportion of said flexible member straight, and an elongated cooperatingmember adjacent to the straight portionof said flexible member arrangedto form a gradual tapering space therebetween.

5. A blank scoring mechanism comprising a pair of endless belts havingstraight portions adjacent to each other and respectively of a tongueandgroove cross section, the direction of movement of said straightportions being slightly angular with respect toeach other to engage saidtongue and groove at one end and to separate them at the opposite end,and rigid guides for holding said adjacent belt portions from lateraldisplacement.

6. A blank'scoring mechanism, compris ing a flexible traveling member,and an adjacent cooperating member, between which material is fed, saidmembers having engaged portions of tongue and groove cross section, themember formed with the tongue having flattened faces at each sidethereof,

opposing beveled faces. formed upon the" other member at each side ofthe groove.

. 7. A blank scoring mechanism, comprising two adjacent members betweenwhich material is fed, having engaged portionsof 20 tongue and groovecross section, the opposing faces at each side of the tongue-and of thegroove being respectively flattened and beveled.

In testimony whereof I aflix my signature 25 in presence of twoWitnesses.
